Determine the maximum load, $P_1,$ that the yellow highlighted $44$ column can support:

Des$$gn Data:

$P_2=50lbs$

$L_c=8$ feet

Assume Douglas Fir$-$Larch No$.1$ lumber for column

Neglect self$-$weight of wood members and connectors, and any uniform loads on the beam

Assume that the dead load only load combination controls the design

Hints:

The $45-$degree brace does not provide support for the column since it won't brace the column from buckling

You will likely have to solve for the maximum load, P$1,$ iteratively, i$.$e$.$ guessing at the load at first, seeing how close the controlling interaction equation is to $1\mathrm{.}0,$ and then refining your load estimate. You may have to do this multiple times, so it is advantageous to setup your problem in Excel or some other computerized solver.
